Not every situation requires a fixed ramp with handrails - ADA allows rises of less than 6" to be resolved with simple curb ramps up to six feet long. Although they don't have handrails, the "Alumilite" line includes integrally-constructed turned-up sides to help keep wheels where they belong. With the same non-skid design of our residential and commercial ramps, these are available in lengths of 3', 4', 5', and 6', and widths of 30" and 36". If you prefer a sturdy folding ramp to a one-piece unit, no problem and no extra cost.
These ramps require no effort to install other than putting them in their place - however, if you'd like to secure them, all you need to do is drill two holes in the surface the top will rest on and insert the two removable pins provided with each ramp.
